To all whom it may concern." the overlapping-lugs for securing the wholeBe it known that I, THOMAS B. JEFFERY, together.

a. citizen of the United States, residing at My invention will be morefully described 'Kenosha', county of Kenos ha, State of Wisheremafterwith reference to the accdmpany- COIlSll'l, have inventeda certain newand use mg drawing in which the same is illustrated clare the followingtobe a full, clear, and

p wh ch form a part of this specification.

. from the provide a vehicle wheel around the ends of ful Improvement inVehicle-Wheels, and de-' as embodied in two convenient tical forms, andin which- Figure 1 is aside portion of a vehicle wheel invention; Fig. 2of the rim and prac" exact descriptionof the same, such as will enableothers/skilled in the art to which it. pertains to make and use thesame, reference being bad to th cmbodyin my an elevational view 0 *one Ilugs-the rim beingshown in sec tion; Fig. 3a sectipnzdviewl on line 3 3Fig. 1; Fig. 4 a view similar to Fig.1 showing a modified form of myinvention; Fig. 5 a sectional. v ew'; and Fig. 6 a sectional view.

Similar reference designate similar of the drawings.

Reference letter A designates a rim about which a pneumatic tire isadapted to be detachably. secured. For convenience I have shown aclencher type of rim.

y invention relates in general to vehicle wheels, and more particularlyto wheels having removable tire-supporting rims.

In the use of pneumatic tires inconvenience and labor are occasioned bypunctures, as it is then necessary to remove the tire rim and securethereon a new tire,

characters are used to parts in the several figures and to remove andrepair the after which the tire must be inflated. Considerable loss oftime and trouble are consequently occasioned by the puncture of any formof pneumatic tire owing to the necessity of'removing the tire from therim.

The primary object of my invention is to punctured one,-

upon the rim C, designate the main spoke members of a vehicle wheel.

I), indicate semi cylindrical lugs or caps secured to the ends of themembers (I, y any suitable fastening devices, such for instance as arivet'zl, extending through' the lower portion of the lug and theadjacent portion of the main spoke member. A screw 03 may also beprovided extending through the upper end of each .lugiD and intotheunderlying portion of the adjacent main spoke member. Theradial edges ofeach lug D is provided with teeth inwardly directed.

E, E designate semi-cylindrical lugs or ,sleeves secure to the innersurface of the rim A at, distancesapart corresponding to the spacesbetween the ends of the spokes. e lugs E n ay 'be secured to the innermin the spokes of which a fully inflated pneumatic tire may be quicklyand easily secured, thereby avoidingthe necessity of repairing apunctured tire on the road and of inflating the repaired tire, or forthe punctured tire.

A further object of my invention is to provide a vehicle wheel, thespokes of which are adjustable in length so that tire supporting rims ofdifferent sizes may be detachably secured around the wheel. 7

A still further object ofmy invention is to provide a detachable t''e-suppor ting nimfor vehicle-'wheels which will be simple inconstruction, inexpensive .in manufacture, and efficient in use. v

The embodiment of my invention herein disclosed may be generallydescribed as consisting of a vehicle wheel having lugs scoured upon theends of the main spoke meni- The radial provided with out- Thecross-section is such as to extend approxihers, lugs projecting inwardlyfrom the rim mately half way around the main spoke adapted to over-lapthe lugs on the ends of member so that the teeth on the edgestheretheniainspok'e members, the cngagingsurof will engage with theteeth on the, 5'60!- face's of the overlapping-lugs on.the rimrespondinglug I).

and spokes having transverse oppositely directed teeth,

and bolts extending through B lndicates a pneumatic tire supportedfaceof the un in any suitable manner,as by elevatio infl view of a aroundthe ends of the main spoke members,

such for instance as bolts F and F extending through holes in the lug Dand through elongated slots 0 in the diametrically opposite portion ofthe lug E.

In 4, 5, and G I have illustrated a modified form of my invention inwhich the lugs project beyond'the ends of the main spoke members andover-la p the correspond ing lugs on the rim. Reference letters G, Gdesignate the lugs which are secured to the main spoke members by anysuitable fastening devices, such for instance as rivets j. The portionsof the lugs which project beyond the ends of the main spoke members areprovided with transverse inwardly directed teeth y. II, II designatesthe lugs which are secured to the inner surface of the rim A, and whichare provided with transverse outwardly directed teeth [1 Any suitableclamping devices maybe used for detachably retaining the over-lappinglugs on the spokes and riln in engagement such for instance as bolts Kwhich extend through holes in the lugs (,ir and through elongatedslots-h in the lugs H.

The rim and tire thereon may be readily detached from the wheel byremoving the clani 'iing bolts so that the over-lapped lugs may beseparated. A new rim with a fully inflated tire may then be securedaround the main spoke members by bringing the lugs thereon into contactwith the lugs on the ends of the spokes. The bolts are then insortedthrough the registering holes and slots in the'lrq's so as to clamp theoverlapped lugs tightly together. It is obvious that the tightening ofthe clamping bolts throws the engaged teeth into close engage. ment sothat when the teeth do not come into exact register the inclinedsurfaces of the teeth tend to forcelhe rim outwardly, inasmuch as theteeth on the spoke-slugs are inwardly directed and the teeth on therimlugs outwardly directed. It is also evident that by the use of myinvention it possible that rims of slightly ditl'erent diameters may besecured to the same wheels, inasnmch as the lugs overlap sullicientl yto permit a cureengagement to be etl'ected even though the rims may varyin size.

From the foregoing description it will be observed that l have inventedan improved vehicle wheel comprising a detachable tiresupporting rim andspokes adjustable in length, the over.lapping lugs in ellectconstituting portions of the spokes. lt is also obvious that by theemployment of my invention the rims may be readily secured around theends of the spokes and at the same time 'l'orced outwardly so as toobviate any play between the rim and the wheel which it surrounds.

While .l. have described more or less precisely the details ofconstruction, I do not through a hole wish to be understood as limitingm self thereto, as I contemplate changes in orm, the proportion ofparts, and the substitution of equivalents, as circumstances may suggestor render expedient without departing from the spirit of my invention.

Having now fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In a vehicle wheel, the combination with the main spoke nilimbersthereof, of lugs secured upon the ends of the said mem; bers, adetachable tire-supporting rim surrounding the said members, lugsprojecting inwardly from said rim and over-lapping the aforesaidlugs,transverse teeth on the engaging surfaces of. the over-lapped lugs, andmeans for securing the lugs together with the teeth thereon interlocked.

2. In a vehicle wheel, with the main spoke members thereof, of lugssecured to the ends of the said members, a detachabletire-supporting rimsur rounding the said members, lugs projecting inwardly from said rimover-lapping the lugs on the said members, and bolts clamping theover-lapped lugs together extending through a slot in one lug of eachover-lapped pair and through a hole in the other lug of each pair. v

3. In a vehicle wheel, the combination with the main spoke membersthereof, of lugs secured upon the ends of the said members, atire-supporting rim surrounding the said members, lugs projectinginwardly from said rim and over-lapping the aforesaid lugs, transverseteeth on the engaging surfaces of the truer-lappinglugs, and bolts forclamping the over-lapped lugs together extending through a slot in onelug in each 'pair and in the other-lug of each pair.

l. lu a vehicle wheel, the combination with the main spoke membersthereof, of lugs secured upon the nds of the said members, atire-supporting rim surrounding the said n,-embers, lugs projectinginwardly from said rim over-lapping the aforesaid lugs, transverse teethon the engaging surfaces of said lugs. the teeth on the spoke-lugs beinginwardly directed and those on the rim-lugs being outwardly directed,and means for clamping the over-lapped lugs together with their teethinterlocked.
